Dungeon Map Doodler Beta - Free online map drawing tool
This is a D&D map making tool I've been working on for a while now, but I just added some new features to the beta that I think HN users might find neat. When building a world map, you can use "Dynamic Brushes" to draw organic looking terrain. This is achieved entirely with svg filters and javascript canvas, no fancy libraries or anything. This came with a pretty large rewrite of some of the underlying code, so I'm sure there's a number of bugs I haven't come across, but I'd love to hear your opinions on it!

In plain words
Dungeon Map Doodler Beta is a free online tool for creating D&D maps. Users can draw world maps and terrain using Dynamic Brushes that produce organic-looking results through SVG filters and JavaScript canvas without external libraries. The tool is designed for tabletop game creators who need to visualize their game worlds. A recent rewrite added new features to the beta version, though the creator notes potential bugs may exist.

Super Map World2023 · supermap.world · ▲115Hi HN I’ve been working on Super Map World, a creative mapping platform and just launched a new animation feature. Try it: https://supermap.world/tools/map-animation What it does: The feature lets you animate maps directly in your browser with a few clicks. You can animate routes, regions, or just simply see a globe in your chosen style rotate from point to point. It’s designed for people who want to make short visuals e.g. social clips, or storytelling maps without needing to figure out GIS tools. Under the hood: Everything runs client-side. I'm using d3.js to render the…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

I'm a big fan of the BBC podcast In Our Time -- and (like most people) I've been playing with the OpenAI APIs. In Our Time has almost 1,000 episodes on everything from Cleopatra to the evolution of teeth to plasma physics, all still available, so it's my starting point to learn about most topics. But it's not well organised. So here are the episodes sorted by library code. It's fun to explore. Web scraping is usually pretty tedious, but I found that I could send the minimised HTML to GPT-3 and get (almost) perfect JSON back: the prompt includes the Typescript definition. At the same time I…
